The first independent analysis of backscatter x-ray body scanners corroborate the claims EPIC and others have made for several years: The scanners are invasive and ineffective. In a detailed report published in 2005, EPIC warned that the x-ray body scanners amounted to a virtual strip search and were an ineffective means of airport security. Freedom of Information Act documents later obtained by EPIC revealed that TSA could disable the body scanner's privacy settings, the nude images could be stored on the machines, and the scanners ran on a standard operating system making them vulnerable to outside security threats. EPIC and a coalition of civil liberties organizations then petitioned DHS Secretary Napolitano to suspend the program. When the DHS failed to do so, EPIC sued the agency. The D.C. Circuit Court of Appeals ruled in EPIC v. DHS that the agency must begin a public rule making. The backscatter X-ray scanners were subsequently removed from US airports.
